A vulnerability classified as critical has been found in Tenda RX9 and RX9 Pro 22.03.02.10/22.03.02.20. Affected is the function sub_42EEE0 of the file /goform/SetStaticRouteCfg. The manipulation of the argument list leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
